Question

how to find cross and dot products of vectors ???​

Answer 1

Explanation:

The cross product of and is defined and best memorized as the expansion of a 3 by 3 determinant: × = = − + . The cross product of and is a vector, with the property that it is orthogonal to the two vectors and . Thus, if we take the dot product of × with and then × with , we get zero both times: × ∙ = 0, and × ∙ = 0.

Answer 2

how to find cross and dot products of vectors ???

answer :-We can calculate the Cross Product this way:

So the length is: the length of a times the length of b times the sine of the angle between a and b, Then we multiply by the vector n so it heads in the correct direction (at right angles to both a and b).
